Description

Technical Field

[0001] The present application relates to a building roof repair and reinforcement node, and belongs to the technical field of existing building repair. Background Art

[0002] During the use of existing buildings, some exterior walls and roofs will be weathered and peeled due to long-term exposure. In order to extend their service life, they usually need to be repaired and reinforced. At present, the most common repair and reinforcement in the industry is steel structure. Steel structure can not only be prefabricated, but also can be reinforced by tie-tying, which is convenient for construction.

[0003] However, there are also a series of problems in the process of steel structure reinforcement. For example, steel structures are prone to rust, have poor fire resistance, and are prone to a series of safety problems after long-term use. At the same time, due to the diversity of buildings, it is impossible to unify the standards for steel components, resulting in different specifications of steel components. In particular, some buildings with historical backgrounds usually need to retain the exterior walls of buildings with certain style characteristics during the repair and reinforcement process. The common steel component reinforcement method cannot meet the requirements of retaining the exterior wall style. Although the concrete method can retain the exterior wall style to a certain extent, it lacks economical and effective reinforcement nodes. Utility Model Content

[0004] In view of this, the present application provides a building roof repair and reinforcement node, which not only realizes the repair and reinforcement of the building, but also realizes the protection of its exterior wall style characteristics.

[0005] Specifically, the present application is implemented through the following scheme:

[0006] A building roof repair and reinforcement node comprises a decorative wall and a structural support beam, wherein the decorative wall is located on the structural support beam.

[0007] A vertical reinforcement node is arranged on the inner side of the decorative wall, and the vertical reinforcement node includes a reinforcement layer, a leveling layer and a waterproofing coiled material layer arranged in sequence, and the reinforcement layer is fixed to the inner side wall of the decorative wall;

[0008] A transverse reinforcement node is arranged above the structural support beam, and the transverse reinforcement node includes a slope layer, a leveling layer, a waterproof coiled material layer, a plastic foam board and a protective layer, and the slope layer, the leveling layer, the waterproof coiled material layer, the plastic foam board and the protective layer are arranged in sequence from bottom to top;

[0009] A tension beam is arranged at the angle between the decorative wall and the structural supporting beam, the tension beam and the reinforcement layer are connected by reinforcement, a plastic foam board and a protective layer are covered on the tension beam, and a water guide ditch is formed on the protective layer close to the decorative wall.

[0010] The above scheme forms vertical reinforcement nodes and transverse reinforcement nodes between the original decorative wall and the structural supporting beam of the building roof respectively. The inner and upper sides are used as the distribution positions of the reinforcement and repair nodes, and tension beams and water diversion ditches are set at the angles between the decorative wall and the structural supporting beam. The former cooperates with the reinforcement to achieve horizontal traction to ensure the firmness of the decorative wall, while the latter facilitates the diversion of rainwater to avoid corrosion of the structural supporting beams and decorative walls caused by rainwater retention. While achieving the corresponding roof reinforcement, the decorative wall can be well preserved.

[0011] Further, as a preference:

[0012] A steel mesh is arranged in the reinforcement layer.

[0013] The plastic foam board of the vertical reinforcement node and the plastic foam board of the horizontal reinforcement node are an integrated structure, which is not only convenient for processing, but also achieves full coverage repair including the angle position when the self-structural supporting beam is laid to the decorative wall, which is more conducive to waterproofing and corrosion prevention.

[0014] The slope leveling layer is a lightweight aggregate concrete slope leveling layer, which is formed as a node closest to the structural supporting beam, and gives the transverse reinforcement node the effect of light weight, heat preservation and heat insulation.

[0015] The reinforcement is an "X"-shaped steel bar, which is arranged in the node position to enhance the connection strength at the node.

[0016] The protective layer has a built-in bidirectional steel mesh.

[0017] A top reinforcement node is arranged on the top of the decorative wall, and the top reinforcement node includes a tension beam and a pressure top, the tension beam is located above the vertical reinforcement node, the pressure top is located above the vertical reinforcement node and the decorative wall, and the tension beam and the pressure top are connected by reinforcement. More preferably, a corner brick is arranged at one end of the pressure top located outside the decorative wall.

[0018] The reinforcement nodes of the above structure are provided with transverse reinforcement nodes on the structural supporting beams and vertical reinforcement nodes on the inner side of the decorative wall. The transverse reinforcement nodes and the vertical reinforcement nodes form a reinforced beam. The connecting nodes such as the angle between the structural supporting beam and the decorative wall and the top node are equipped with "J"-shaped steel bars to make the vertical and transverse reinforcement nodes form a whole. The roof and parapet of the original building are reinforced, and the reinforcement of the roof, top and other parts is completed. The mechanical properties are improved by 20% to 30% compared with the conventional steel structure reinforcement. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] This embodiment is a building roof repair and reinforcement node, combined with Figure 1 , including a decorative wall 1 and a structural supporting beam 2, wherein the decorative wall 1 is located on the structural supporting beam 2.

[0023] A vertical reinforcement node 3 is arranged on the inner side of the decorative wall 1. The vertical reinforcement node 3 includes a reinforcement layer 31, a leveling layer 32 and a waterproof membrane layer 33 arranged in sequence. The reinforcement layer 31 is fixed to the inner side of the decorative wall 1 by filling slurry (60 mm thick).

[0024] A transverse reinforcement node 5 is arranged above the structural supporting beam 2, and the transverse reinforcement node 5 includes a slope layer 51, a second leveling layer 52, a second waterproof membrane layer 53, a plastic foam board 54 and a protective layer 55. The slope layer 51, the second leveling layer 52, the second waterproof membrane layer 53, the plastic foam board 54 and the protective layer 55 are arranged in sequence from bottom to top.

[0025] A second tension beam 6 is arranged at the angle between the decorative wall 1 and the structural supporting beam 2. The second tension beam 6 is connected to the reinforcement layer 31 by a second reinforcement 61. A plastic foam board 54 and a protective layer 55 are covered on the second tension beam 6. A water guide ditch 7 is formed on the protective layer 55 on the side close to the decorative wall 1 at the thinnest part of the slope layer 51. The side wall of the water guide ditch 7 close to the second tension beam 6 is a right-angle wall, and the side away from the second tension beam 6 is a slope wall. The second tension beam 6 adopts a square structure with a width of about 150 mm. The reinforcement 61 arranged therein is a "J"-shaped steel bar; the width of the water guide ditch (including the width of the slope wall) is about 300 mm.

[0026] The above scheme forms vertical reinforcement nodes 3 and horizontal reinforcement nodes 4 between the original decorative wall 1 and the structural supporting beam 2 of the building roof, respectively. The inner side and the upper side are used as the reinforcement and repair node distribution positions. The processing process is as follows:

[0027] In the first step, the original wall of the decorative wall is retained, and grouting (containing a steel mesh with a diameter of 8 mm) is performed on the back of the decorative wall to form a reinforcement layer 31. The structural supporting beam 2 is reinforced with steel bars to form a roof panel. After the surface is cleaned, a slope layer 51 is formed with LC5.0 lightweight aggregate concrete at a slope of 2%, forming the prototype of the water diversion ditch 7.

[0028] In the second step, grouting is performed near the angle between the reinforcement layer 31 and the structural supporting beam 2 to form a square second tension beam 6. A "J"-shaped steel bar is arranged in the grouting as the second reinforcement 61. The second reinforcement 61 is tied and fixed to the steel mesh in the reinforcement layer 31.

[0029] In the third step, after the second reinforcement 61 is formed, a leveling layer 32 is formed on the surface of the reinforcement layer 31 with DS15 cement mortar; and a leveling layer 52 is formed on the slope layer 51 with DS15 cement mortar.

[0030] The fourth step is to apply a layer of base treatment agent and a polymer modified asphalt waterproof coating with a thickness of about 3 mm on the leveling layer 32. The leveling layer 2 52 can be treated in the same way and then covered with a polymer modified asphalt waterproof membrane with a thickness of about 3 mm. The waterproof membrane 2 53 is placed above the structural supporting beam 2 and the waterproof membrane 1 32 is placed on the inner side of the decorative wall 1. At this time, the vertical reinforcement node 3 is basically formed, and the waterproof membrane covers the self-leveling layer 1 32, the second tension beam 6 and the leveling layer 2 52.

[0031] The fifth step is to install an extruded polystyrene foam board with a thickness of about 60 mm on the waterproof membrane 2 53 to form a plastic foam board 2 54 .

[0032] In the sixth step, C20 fine stone concrete with a thickness of about 40 mm is poured on the second plastic foam board 54, and a bidirectional steel mesh with a diameter of 5 mm@150 is arranged in the fine stone concrete to form a protective layer 55, thereby the transverse reinforcement node 5 is basically finalized.

[0033] In this case, the decorative wall 1 is retained as a whole, and vertical reinforcement nodes 3, transverse reinforcement nodes 5, water diversion ditches 7, and second tension beams 6 are respectively formed on the inner side of the decorative wall 1, above the structural supporting beam 2, and at the angle between the two. The vertical reinforcement nodes 3 and the second tension beam 6 cooperate with the second reinforcement 61 to achieve horizontal traction to ensure the firmness of the decorative wall 1, while the transverse reinforcement nodes 5 and the water diversion ditches 7 facilitate the diversion of rainwater to avoid corrosion of the structural supporting beam 2 and the decorative wall 1 caused by rainwater retention.

[0034] During the repair and reinforcement process, a top reinforcement node 4 can also be set at the top of the decorative wall 1. The top reinforcement node 4 includes a first tension beam 41 and a pressure top 42. The first tension beam 41 is located above the vertical reinforcement node 3, and the pressure top 42 is located above the vertical reinforcement node 3 and the decorative wall 1. The first tension beam 41 and the pressure top 42 are connected by a first reinforcement 43.

[0035] During repair, you can first tie a "J"-shaped steel bar on the steel mesh of the reinforcement layer 31 as the first reinforcement 43, and then cast to form a square first tension beam 41. The first tension beam 41 is located directly above the second tension beam 6 and slightly protrudes from the inside of the vertical reinforcement node 3 in the horizontal direction. Then, pour concrete on the top of the decorative wall 1 and the top of the remaining vertical reinforcement nodes 3 to form a capping 42.

[0036] If necessary, a red brick sheet specially used for cornering is installed as a corner brick sheet 44 at the corner of the top cover 42 facing the outer side of the decorative wall.

[0037] After the above-mentioned reinforcement nodes are processed, the structural support beams below the decorative wall 1 can be painted with yellow cement, and tiles can be pasted as needed to form an exterior decorative layer 21.

[0038] The reinforcement nodes of the above structure are provided with transverse reinforcement nodes 5 on the structural supporting beam 2, and vertical reinforcement nodes 3 and top reinforcement nodes 4 are provided on the inner side of the decorative wall 1. The transverse reinforcement nodes 5 and the vertical reinforcement nodes 3 form a reinforcement beam. The connecting nodes such as the angle between the structural supporting beam 2 and the decorative wall 1, the top node and other positions are provided with "J"-shaped steel bars (such as the first reinforcement 43, the second reinforcement 61, etc.), so that the vertical and transverse reinforcement nodes form a whole. The reinforcement of the original building roof, parapet, capping and other parts improves the mechanical properties by 20% to 30% compared with the conventional steel structure reinforcement.
